The project was the first time the company performed such work on a light-rail system, R. J. Corman officials said in a press release.

Previously, the company has performed railroad maintenance and construction work on Class Is, regionals and short lines. The company is equipped, however, with all the equipment and skills necessary to service passenger-rail systems, they said.

The job presented unique challenges: It needed to be completed in a 48-hour window and the track was located in a densely-populated area, company officials said. Three crews used tampers, rotary dump trucks, welding trucks and other specialty on-rail equipment.

Rail adjustments were necessary to remediate sun kinks.

The project was completed in 38 hours without injuries or lost-time incidents, according to the company.
